Abstract:
Much development aid over the past 40 years has been devoted to family planning on the assumption that information and supply constraints for contraceptive services result in families larger than demanded and the welfare of each child in a large family subsequently suffers due to dilution of household resources. However, it is not clear that larger families per se result in worse outcomes, especially if older children play a role in household production or if the marginal cost of child investment is low. An improved understanding of the relationship between fertility and child welfare in developing countries will help inform future policies related to child investments including the targeting of health or education subsidies or conditional aid transfers.
